  • Publication number: 20220253444
    Abstract: An approach is provided for optimizing a database buffer pool. Based on statistics about read and write operations in a range of pages, the range of pages is determined to be a candidate for a hot read range for which locks and latches are avoided in processing operations in the hot read range. Using an on-time trigger or pre-trigger process, the hot read range is created from the range of pages by marking start and end points in the range of pages. Write operation(s) are determined to be included in the hot read range by marking an object control block. The write operation(s) are added to a write pending list. The read operations in the hot read range are performed without a latch or lock. The write operation(s) are merged from the write pending list to the range of pages and the write operation(s) are performed.

  • Publication number: 20220245130
    Abstract: Database log writing is based on log pipeline contention. A determination is made as to whether contention in writing data to a log pipeline, which is used in writing data from memory to storage, is at a prespecified level. Based on determining that the contention in writing the data to the log pipeline is at the prespecified level, a split operation is automatically performed to create a new log pipeline.

  • Publication number: 20220237160
    Abstract: Trace processing in a database system is facilitated by obtaining database trace data collected from database tracing a database system, and data analyzing, by one or more processors, the database trace data to determine one or more field-related rules to, in part, reduce impact on system performance of database tracing in the database system. Trace processing is further facilitated by applying the one or more field-related rules to a database trace in the database system to adjust trace fields of the database trace according to the one or more field-related rules, thereby reducing impact on system performance of the database trace in the database system.

  • Publication number: 20220237742
    Abstract: Systems and methods for processing images receive an input image. The systems and methods provide the input image to a first module to increase a resolution of the input image to produce an upscaled image. The systems and methods detect white pixels in the input image. The systems and methods generate a mask associated with the input image. The mask includes mask bits that are set to mark the white pixels in the input image. The systems and methods upscale the mask to produce an upscaled mask matching a resolution of the upscaled image. The systems and methods identify target pixels of the upscaled image that correspond to the set mask bits in the upscaled mask. The systems and methods modify the upscaled image to produce an output image by replacing target pixels of the upscaled image with a replacement pixel having greater whiteness. The systems and methods output the output image.

  • Publication number: 20220237739
    Abstract: Systems and methods upscale an input image by a final upscaling factor. The systems and methods employ a first module implementing a super resolution neural network with feature extraction layers and multiple sets of upscaling layers sharing the feature extraction layers. The multiple sets of upscaling layers upscale the input image according to different respective upscaling factors to produce respective first module outputs. The systems and methods select the first module output with the respective upscaling factor closest to the final upscaling factor. If the respective upscaling factor for the selected first module output is equal to the final upscaling factor, the systems and methods output the selected first module output. Otherwise, the systems and methods provide the selected first module output to a second module that upscales the selected first module output to produce a second module output corresponding to the input image upscaled by the final upscaling factor.

    Abstract: An approach is provided for automatically updating a data type of a database column. Based on a database definition, category, and usage, the column is determined to be a candidate for a data type change. For first values in the column values, costs of processing queries using a new data type are determined to be less than other costs of processing the queries using other data types. For exception value(s) in the column values, costs of processing the queries using the original data type are determined to be less than other costs of processing the queries using other data types. The original data type is replaced with the new data type for the first values and the original data type is retained for the exception value(s). The first values are associated with a first schema and the exception value(s) are associated with a second schema.
